carb king and '48 are correct. Today's gas is so unstable that it gums up after only a few days. I have a Jeep and a JD 60 that have the same problem because I don't use them often enough.

Sometimes you can squirt spray can carb cleaner into the gas inlet of the carb and this helps for a few days.

The best thing is to take the carb bowl top off and dip the whole thing, float and all, into Berryman dip carb cleaner for a few minutes. This will clean almost any gum off andit will stay clean if you use it often. If you don't the problem will eventually return.
